If they give us the whole game, the more advances guardians would have it bear far before everyone else, which would be unfair, not to mention not any fun. Releasing it in parts, is obviously more costly, but I feel it's more efficient. Everyone has the same chance and amount of time to reach the highest level within the given expansion. Everyone has time to do the raid, again more advanced people obviously have completed it a lot more, but seeing as there is only SO much raid gear you can get, it gives those of us who aren't as good more time to catch up for the next expansion to come out. Although they're doing it for more money, I feel people fail to realize the good it's actually doing.
